The MPEG-PS muxer uses a custom queue of custom packets. To keep track
of it, it has a pointer (named predecode_packet) to the head of the
queue and a pointer to where the next packet is to be added (it points
to the next-pointer of the last element of the queue); furthermore,
there is also a point

mxf distinguishes codec profiles by different UIDs and therefore needs

is a defined UID for it). If not, then sometimes the UID would be set to

The mxf_d10 muxer is very picky regarding the input it accepts:

The md5 test up until now ignored errors from ffmpeg (the cli) and just
md5'ed whatever ffmpeg has output; while testing scenarios in which
ffmpeg fails has its merits, errors should not be overlooked by default;
doing so also reduces the effectiveness of sanitizers as errors from
them are ignored.
Normally, video packets are muxed before audio packets for mxf (there is
a dedicated interleave function for this); furthermore the first (video)

The only samples I found have the extension pbm and I
simply misunderstood how you designed this since my
samples were detected as pbm (because of their
extension).
Will fix, Carl Eugen

Hi!
Attached patch is necessary for a new pfm demuxer.

A parser cannot support more
While this is mode source code, it generates less binary code and can be
more cleanly extended to H.266.

Can't we just wait and increment the number of codec_ids a parser can
support at the next bump?
